BACKGROUND

The current invention is co-inventor same concept with the U.S. Pat. No. 6,179,431 Dec. 24, 1998 filed. The difference between the parent patent of '431 with current invention mainly at the night light use Light emit diode (hereafter as LED) instead of the Electro-luminescent night light.

The major difference compare with other conventional LED power failure night light at the batteries application. The all other prior art preferred to use the Rechargeable batteries as power source for the emergency light which is very bad because (A) the capacity of the rechargeable battery normally is much less than the non-rechargeable battery. Such as for AAA size battery the rechargeable battery only have 650 ma and the capacity of the non-rechargeable can have 1,000 ma to 1,200 ma for Duracell brand which are the most common battery used in North American.

Not only for the capacity of the battery between rechargeable and non-rechargeable have big difference.

But also (B) the rechargeable battery normal have potential risk for fire hazard. It is very often to hear the cellar phone or flip top computer rechargeable battery exploded so this is the most dangerously to use the rechargeable battery for the power failure night light because the power failure night light normally plug-in wall outlet if the inner rechargeable battery exploded it will cause big house burn or burn down all the electric arrangement of house. It will be big damage to people house and electric system and need pay million dollars to repair the house or electric system. If have any people injury or cause death, it will be unforgiving for the bad products.

And, (C) To use rechargeable battery as power source for emergency light need extra cost for the recharge circuit which need more safety electric components such as surge protection, high voltage impact protection to make this circuit can prevent any thunder hit on the house electric system. This will let people to pay for much more cost for these extra protection circuit and electric components so rechargeable batteries are very costly. (D) The rechargeable battery normally still have memory problem, If people do not plug the rechargeable battery device for fist 12 or more hours. It may only charge ¼, ⅓, ½, ¾. ⅔ battery capacity such as AAA battery for 650 ma, then battery only can be charge on following times only 650/4, 650/3, 650/2, 650×¾, 650×⅔ because the battery memory problem and there is no any rechargeable battery have 100% fully rechargeable quality. (E) The degrading of the rechargeable battery, Normally the rechargeable battery have limited cycles to charge the battery and some battery will quickly to degrading and only have very limited cycles to recharge such as 10 time or 50 times or 100 times depend where and which company to make the batteries.

From above (A) (B) (C) (D) (E) bad problem of the rechargeable battery and all current market power failure light also use China made cheap rechargeable batteries without any well-known company to endorse after strictly testament so it is too big risk to use rechargeable battery for this important outlet plug-in device for people use at home.

The current invention solved not only the most fatal concern for rechargeable battery of above (A) (B) (C) (D) (E) concern. But also incorporate the co-pending filing parent patent including more than 1 light source, more than 1 function, more than 1 optics means, interchangeable power source, project light, LED light with special function, more than 1 reflective means as above listed continuity list as parent filing. The current invention also has all those co-pending filing scope can applied to current invention with those features.

Basing on this persistence of vision of human eye response time within 1/24 (41.67 msec) to 1/16 (0.0625 sec) second so while the object move faster than the human eye response time can make the last image stay in human eye and brain for a period of time of the last image. This theory can further use for LED or LEDs because LED or LEDs response time is very short which around 10 msec or less. Hence, If object show in front of human eye more than 16-24 pictures, than people will think all pictures are continuously. Hence, current invention further to use related circuit, control means, IC, micro controller to make the said LED or LEDs light device with blinking of said LED or LEDs with much faster than the 16-24 times (cycles) per second and make each cycle with 10% for turn-on and 90% for turn-off of the said LED or LEDs, then, can save up to 90% of the power consumption or we can say the battery life can increase 9 times than full steady-ON condition. This is really a power saving for all battery power source application. It is appreciated that the new LED technical may coming soon to make the LED with more quickly response time less than 10 msec, it maybe 5 msec time or 2 msec response time so can let more power saving. To adjust the Duration time of each cycles for turn-on and turn-off duration time will make more power saving device to meet green world concept. This is the other very important concept of current invention.

Further for Cost saving of battery powered unit to use less battery which lower than LED or LEDs trigger voltage battery number on device and use circuit with proper electric components and parts & accessories to make the battery's lower voltage to raise-up to higher voltage to trigger the said LED or LEDs can use less battery number for device. This can reduce people to use many quantity of battery and save the cost to make battery operated LED light unit is other important concept for current invention.
